Best Practices for Sealing HVAC Systems

Energy Star programs are requiring more expertise from HVAC crews. Here are some helpful training hints.

Recently I wrote a guide for the Northwest Energy Star New Homes program. The guide is designed to help instructors address the training needs of HVAC installation crews who have little or no experience in duct leakage testing. The goal of this training is to give HVAC contractors the information they need to seal new HVAC systems effectively. Key to achieving this goal is the trainer’s ability to mesh the techniques of creating an Energy Star sealed air duct system with the manufacturer’s new-construction installation procedures.
